I, for one, am very pleased with this Nexus lineup (disclaimer: I work for Google).
The Nexus 4 for $299-349 seems to be outstanding value given the competition is typically ~$600 unsubsidized. I also consider the lack of LTE to be a feature. LTE chipsets are still immature, to the point I'm almost surprised Apple has adopted them. I don't know what they add in cost but they certainly, by all accounts, drain battery life.
The Nexus 7 for $199 seems to be outstanding value. Google Play isn't quite the iTunes ecosystem yet but it's getting much better. I also think it's better than an iPad Mini in that it's widescreen not 4:3. I've lined up a Nexus 7 against my iPad playing Netflix. Playing widescreen the Nexus 7 is only marginally smaller. 720p seems to be a good baseline to aim for on this size of device (IMHO).
I'm also pleased to see the Nexus 10 for $399. It looks like a very nice device.
I also think Android is starting to coming into its own. I've often been critical of it compared to the consistency, ease of use and general pleasure of iOS but that shortcoming is rapidly disappearing.
I compare it to the Motorola Droid, which I have. It's a terrible phone. Everything about it is just bad.
My only gripe with Android phones these days is that they continue to get bigger. I like the form factor of my iPhone 4S.
Plus the Nexus devices has the vastly superior Google Maps. :_ I for one like having public transit directions on my maps.
